I have a blank device that returns the following info string from the UART downloader:
ADuCM302x 421-FW- 0179EB0A73E2CD932201400013736333
After the revision numbers, the first '-' indicates the usercode is blank.
The second '-' indicates that read protection is enabled.
Is this correct? The kernel docs indicate that if usercode is blank that read protection should be disabled.
